WATER FILTER. i

Application filed February `Another object oiiour invention isto provideal filter which .may be readily taken apart for cleaningand replacementof parts and which maybe again quicklyassembled. A furtherrobjectis 'toprovidea filter which is simple in construction'and effective inoperation. V

Other objects, advantages,l and features of invention mayv appear fromthe accompanyy ing drawing, .the subjoined detailed descrip,-

tion, and the appended claims.

In the drawing- H F ig. 1 is a longitudinal -sectional view of ourimproved filter.V`

Fig. 2 is a longitudinal sectional view ot a slightly modified form offiltering element.. i

Referring ing:

Our filter comprises an upper container '1 and a lower container 2.Acovcr 3 is provided on the upper container whereby the water in saidcontainerl may be replenished. The container 1 is provided with a basin4 which fits withinl the container 2 and a shoulder 5 on the container 1`rests on top of the container 2, thus mounting the containers injuxtaposition.

A filtering element 6 is positioned in the basin 4 and comprises a tray7 having upturned edges 8 and a central spout 9. The spout 9 extendsthrough the bottom of the basin l and a rubber gasket'lO is providedaround said spout thereby preventing leakage of water past said spout.An annular wall 11 rises'trom the tray 7 and is integral therewith, andwithin the vvall 11 we place a bed of vegetable and mineral filteringmaterial (such as charcoal)A 12. Above the charcoal bed 12' we provide alayer of asbestos felt, or the like, 13. A fine screen 14 rests on thebottom of the filtering element 6 and extends over the spout 9.

In order that the water which enters over the annular wall 11 shall notpass downwardly adjacent said wall and thus not enter more particularlyto the drawthe charcoal and asbestos, we have provided a fiat ring 15 atthe top ot the wall 11 there- 2s, 1927. serial No. 171,418.

by directing the water towardszthe center and compelling its' passagethrough the asbestosand charcoal before may enter the compartment,saidring-being integral With the wall 11 Aand `formed by bending theup'- per end inwardly.

The tray 7 and wall 11 isy formed ofamaterial which is'impervious towater.` A ceramic filtering cup 16 extends overA the Wall 11, thebottom-thereof ,resting in the tray 7, and asuit'able cement, asshown at17, seals the bottomiof the cupA 16 thus preventingv the passage ofwateraround the bottom thereof. l

The'water passing through the ceramic cup 16 hasmost'of the impuritiesremoved therefrom and in passing through the asbestos layer 13- andcharcoal bed,12A the water is bleached and .enters the compartment 2 ina clear and pure condition. .`A'sp`out\18 enables tlie water lto bewithdrawn from the compartment 2; A

In Fig. 2 we have'showna slightly modiiedorm ot filtering element. Thetray 7 isi providedfwith an annular wall' 17 rising therefrom and yaplurality of lips 18 arel provided adjacent vthe vupper endthereof,

and; a rubber ring 19 fits under saidlips. The ring 19 is preferably.split .and provided with a spring ring therein which holds they ring 19securely against the Wall 17, thus packing ofi" the wall at the topthereof' and causing 'the Water to pass over the ring 1 and enter thecharcoal bed 12. y

lhen it is desired to clean our filter it is only necessary to removethefilter element 6 from the compartment land by melting the cement 17 thecup 16 is removed yexposing the charcoal bed 12 and asbestos layer 13which may be quickly and easilyy replaced.

To hold the asbestos layer 18 and charcoal bed 12 securely in placewemay provide a spring ring 2O under theflat ring 15 Which pressesdownwardly on the said layers to hold them securely in position.

Having described our invention, we claim: 1. A water filter comprisingupper and lower compartments, a'filter element in said' uppercompartment comprising a tray Vimpervious to water, a vspout dependingfrom said tray and extending into the lower compartment, an annular wallrising from said tray, said wall being impervious to Water7 a ceramicfiltering cup positioned yover said wall, and resting in said tray, and`means to direct the water towards the center of the space inclosed bysaid annular Wall.

2. A water filter comprising vupper and lower compartments, a filteringelement in said upper compartment comprising a tray, a spout 'dependiligfrom said tray and extending into the lower compartment, an annularvwall rising from said trayfa ce'- ramic filtering cup positioned oversaid wall and resting in said tray,a1`id"1neansto direct the watertowards the center of said annular u'alhs'ai'd ipeanslcomprising anannular ring extending inwardly from said annular' wall, a charcoal bedon the trayz within the wall, anda screen under said charcoal bed, saidscreen extendingr over said spout.

A water filter comprising an upper compartment and Va lower compartment,said upper compartment' beingv provided with a basin adapted ,to 4fitinto the lower compartment,` a filtering element positioned in saidbasin, said Afiltering"element comprising a tray, sproutdepending 'fromsaid'tray, said spout extending through the basin into the lowercompartment, a rubber packing about the spout, an annularlwall'rising'from the tray, said annular wall ,being adapted to en-Yclose a" vegetable and mineral filter bed, I neans adapted to direct thewater towards the center of said filter bed` a ceramic filter cupextending'over saidfwall and resting in the tray, and means to seal thebottom of said lfilter cup. i' l 4; A water filter comprising an uppercompartment and a lower compartment, vsaid upper compartment beingprovided Vwith a i basin adaptedbto fit/into the lower cornpartinent, alfiltering element positioned in said basin, said filtering. element*comprising a tray, la spent depending' from said tray,
